AMALGAMATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 726,997, dated May 5,1903.

Application filed July 11, 1901.

My invention relates to the improvement of amalgamating devices; andthe'objects of my invention are to provide improved means for subjectingore-pulp to the action of mercurially-treated amalgamating material; andto this end my invention consists in ,certain details hereinafter set,forth. Theseobjects I accomplish in the manner-illustrated; in theaccompanying drawings, iniwhich Figure 1 is a central longitudinalsection of my improved amalgamating device, and Fig. 2 is a plan view ofthe same.

Similar numerals refer to similar parts throughout both views.

In carrying out my invention-I;employ an elongated receptacle 1, whichisprovided in its upper portion and at one end with an inlet 2 and at itsopposite end with an outlet 3. The receptacle 1 is suitably mounted orsupported and has rising from its opposite sides and adjacent to itsendsstandards 4, the upper ends of these standards being provided withsuitable keepers 5. In the bottom and preferably near the center of thelength of the receptaclel I provide a transverse well or offset 6,which-is incased by a jacket 7, the latter having a steam inlet 8 andoutlet 9.

10 represents the parallel side bars-0f a horizontally-movable frame,said side bars being supported loosely in the standardkeepers 5.Journaled between the side bars 10 of said sliding frame at desirableintervals are shafts or rollers 1'1,'each 'of" these rollers being.provided at one end with a crank extension 12 or other suitable meansfor aiding inimparting rotary motion thereto. Suspended from each ofthese rollers or shafts by means of cords 13 is a transverseamalgamating case or receptacle 14,"which is formed of suitable open-work..-* Although each of these amalgamating devices is shown as in theform of an open-work casing provided with an internal filling 15, ofamalgaserial No. 67,857. (No model.)

mating substance, it is obvious that I might employ in place of saidcasing a desirable form or character of amalgamating-body.

The Well or offset 6 is designed to be filled or partially filled withmercury, which is kept at the proper temperature by steam containedwithin the jacket 7. The operation of successively dipping theamalgamatingbodies 14 15 into the mercury-well consists in sliding theframe-bars l0 longitudinally until one of said amalgamating-bodies is ina position immediately over the Well 6, from which position it maybellowered into the body of mercury contained in said well. This beingaccomplished, the amalgamatingbody is' by. rotatingthe supporting-shaftthereof drawn upward within the body of the vessel 1, the frame again;moved longitudinally, and the'process of dipping imparted to the'nextsucccceding amalgamating-body. During this process the ore-pulp isintroduced through the inlet or. hopper 2 into the vessel 1, throughwhich it will flow to the outlet 3, the ore-pulp thus being subjected inits passage through said vessel and through the amalgamating devices tothe amalgamating action of the latter and the tailings discharged at theoutlet 3. The immersion of the amalgamating-bodies within the mercuryresults in imparting a mercury coating to said bodies, which. whenbrought into contact with the ore aids'in'the usual manner inseparatingthe pure metal from the ore-pulp. Owing to'the comparativelyhigh specific gravity of the mercury and the resultant difficulty incausing the amalgamating-bodies to descend by gravity-into the'mercury,suitable means may be employed to force said amalgamator-bodies intothemercury. By this operation it will be understood that the amalgamatingdevices are successively dipped into the mercury and elevated intoposition to contact with theore-pulp, thus insuring the subjection ofsaid pulp to the action oflamalga mating-bodies and'in'suring aseparatiofi of the precious metals from the ore. V Having now fullydescribed my invention,- what I claim, and desire to secure by LettersPatent, is-' In an amalgamator, the combination with anere-pnlp-receiving vessel having an offset or well in its lower sideadapted to contain a body of mercury, of amalgamaLing-bodies containedwithin said vessel, a, movable support for said amalgamating-bodiesabove the vessel and means connected with said support for raising andlowering said amalgamating-bodies independently, substantially asspecified.
